How long does it take to compost?

Composting timeframe depends on the exact conditions of the compost. Industrial or commercial composts run at higher temperatures and generally operate on a time frame of 2-3 months. Home composts are more variable and dependent on things like climate and how well they are managed. Home compost certification assumes the compost environment operates ~30°C and in order to achieve certification products must fully biodegrade within 12 months.
